Optimize screen streaming performance and clean up debug logs

- Reduced image processing time from 7-8 seconds to 340-420ms (15-20x improvement)
- Optimized BGRA->RGBA conversion with unsafe pointer operations and batch processing
- Changed image resize filter from Lanczos3 to Nearest for maximum speed
- Reduced target resolution from 400x225 to 320x180 for better performance
- Reduced JPEG quality from 75 to 50 for faster compression
- Fixed force-send mechanism timing from 500ms to 200ms intervals
- Improved frame rate from 0 FPS to ~2.5 FPS
- Cleaned up extensive debug logging and performance instrumentation
- Removed unused imports and variables to reduce compiler warnings
